I built a fairly simple website for a friend of mine who owns a warehouse, and everything seems to be working perfectly on the site, except for one minor issue - there is a bunch of extra space on the right side of all the pages.

You can see what I am talking about if you visit the site - kakllc.com (scroll to the right to see the extra space)

If someone could figure out where this extra space on the right is coming from, I would really appreciate it. I have spent several hours trying to figure out the problem, but am not experienced enough to solve it. Thanks for your time!
